Need some advice: ovulating today!!

I’m so excited!! After my miscarriage in July (2011) I found it hard to track my ovulation day, so i decide to try clear-blue and after twoweek of peeping on a stick, this morning it shows that today is my day!!!!

My only thing is I didn’t do anything for the past twodays.. And a lot of sites say the best time is to do it is two day before...But we did have sex this morning...
